INVESTIGATION OF POSIBILITES FOR SIMULTANEOUS
EXPLOITATION OF COAL AND OIL SHALE IN THE
ALEKSINAC BASIN
Abstract
Following the efforts and activities in other countries that have oil shale, we can see, that this energy
potential is intensive and accounts for winning the technology of their economic exploitation
and processing, in order to obtain liquid and gaseous hydrocarbons and other valuable products.
The scope and structure of energy resources and energy in Serbia is in unenviable situation
and this research attempts to initiate a different approach for utilization the energy resources in
Serbia. With the economic and strategic aspects is need to scientific research forces directed towards
development of utilization the oil shale and reduce dependence on energy imports from the
country.
According to some estimates, the Aleksinac deposit of oil shale is one of our most promising
deposits, and oil shale reserves are estimated at about 2 billion tons, with high content of 9.78%
oil, and contains total of about 190.000.000 t oil. In this paper, we are considering the possibility
of simultaneous exploitation of oil shale and remaining brown coal using the mining method of
longwall and the method of underground gasification.

INTRODUCTION
The scope and structure of energy reserves
and resources of Serbia is very unfavorable.
Reserves of high-quality energy
such as oil and gas are symbolic and are
less than 1% of total balance reserves of
Serbia, while the remaining 99% of energy
reserves are various types of coal,
which dominates low quality lignite, with
the participation of over 92% of total balance
reserves. This is especially true of
lignite that is exploited in the mines with
surface mining, the exploitation by total

reserves of about 13,350 million tons, the
most important energy resources of the
Republic of Serbia. Geographically speaking,
in the Kolubara basin is 14%, in the
Kostolac basin 3.3%, while the Sjenica
and Kovinski basin contain only 2.7% of
these reserves. [6]
The structure of current energy consumption
in every country, caused by the
state of economy in all sectors, including
energy sector, especially the structure and
intensity of production and service
